ABOUT THE TIDE CLOCK
Unlike a regular time clock that goes around in 12 hours, our tide clock travels around in 12 hours and 25 minutes - the average time between high tides in places where tides are mostly regular. Referred to as semidiurnal tides, these are locations that experience two high and low tides of approximately equal size every lunar day.
Is a tide clock always accurate?
During a lunar month (29 days), the tide clock is relatively precise to the true state of the semidiurnal tides. However, 12 hours 25 minutes is an average time, so it can happen that some days the tide clock undergoes slight inconsistencies during a tide cycle. Often times these slight intervals happen locally when there is a storm, or the seasons are changing. This does not always mean you need to adjust your clock, though! The law of averages tells that most future events are likely to balance any past deviation from a presumed average. In fact, you should only need to adjust your clock twice a year after the first day of Spring and the first day of Autumn, as these periods trigger stronger tides.
It is important to note that tide clocks are NOT as accurate as a tide calendar, and therefore not accurate for activities that require precise tidal times. They are more for giving you a general state of the tide so you know when you want to hit the water!
Does a tide clock work everywhere?
The clock itself will physically work anywhere, but, unfortunately, it will not always be accurate everywhere. The fault of the tide clock is that semidiurnal tides are NOT the only kind of tide. For example, the vastness of the Pacific Ocean makes the regularity of tides less predictable. If you live on the Pacific Coast or in Hawaii, there are weekly setting instructions available online for your specific location so that you can have the most accurate readings possible from your clock. The Gulf of Mexico only has one high and one low tide each day, meaning there is not an adjustment that can be made to make our tide clock reflect your tidal times.
